Special Price for Cold Rolled Stainless Steel Coil – Hot rolled steel plate Plate manufacturer Q235 Carbon steel plate – Lu

Introduction

Using continuous casting slab or blooming slab as raw material, it is heated by a walking heating furnace, high-pressure water is descaled and then enters the rough rolling mill. The rough rolling material is cut head, tail, and then enters the finishing rolling mill for computer-controlled rolling. After the final rolling, it undergoes laminar cooling (computer-controlled cooling rate) and coiled by a coiler to become a straight hair coil. The head and tail of straight hair curlers are often tongue-shaped and fish-tail-shaped, with poor thickness and width accuracy, and the edges often have defects such as wave shape, hemming, and tower shape. The coil weight is heavier, and the inner diameter of the steel coil is 760mm. Good ductility, cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The strength of the hot-rolled plate is relatively low, the surface quality is poor (oxidation + low finish), but the plasticity is good, general medium and thick plates, cold-rolled plates: high strength + high hardness, high surface finish, general thin plates, can be used for stamping Use the board. The mechanical properties of hot-rolled steel sheets are far inferior to those of cold rolling and forging processing, but their toughness and ductility are better.
